Inl IW@ NVE/WEE;

of both the gripping and clamping members may be manual, followed by movement through mechanical operation.

As another featureof the invention the carrier for the gripping members, while movable as a whole, as just described, is in sections independently movable while in the active position, this independent movement causing the gripping members to open to prepare for the introduction of the material. Thereafter the sections may move together to bring the edges of the material between the gripping members, which are closed by a further independent movement of the members. The gripping members are arranged oppositely with tension-equalizing means interposed between lthem for the purpose of equalizing the tension on the opposite sides of the material. A succeeding travel of the carrier sections, upwardly, eX- erts tension on the material to draw it about the form, and finally, after the release of the gripping members, the carrier sections are raised together to a point from which they may be swung clear of the form.

Still another feature of the invention concerns the work-engaging means, particularly the clamping members, which come into action after the gripping members to secure the tensioned material against the form in preparation for its final tacking by the operator. These clamping members, like the gripping members, act upon adjacent portions of substantially thel entire length of opposite edges of the material and preferably along practically continuous lines. In the present embodiment of the invention the clamping members at each side of the work are upon a support common to all which may be moved manually to effect a rapid travel of the members from a position clear of the form to their operating position. Then power operated means may finally press the clamping members throu h interposed yieldable connections into t e final clamping position. A further feature relates to means forreleasing the work-en gaging members, such a means being here disclosed applied both to the gripping and clamping members. Vith the latter the eX` pansion of their yieldable connections furnishes means for moving said members and their supports clear of the work.

An additional feature of the invention concerns means for adapting the machine for operation upon different sizes of work. In accordance with this phase of the invention, the shaping members prior to actual engagement with the work aremoved differently for the different sizes, so that they may have a definite relation to said work for all sizes before beginning the shaping operations. As herein described, the extent of approach of the gripping members is variably determined by such means as a controlling member (so-operating with a controlling surface carried by the form support, said support being adjustable to positions dependent upon the size of the leggings being produced.` The position to which the clamping member supports are manually moved may also be varied to correspond to the size, 'this too, being shown as accomplished by the position of thev form support which is `caused to alter the location of an element of the locking means for the supports.

The foregoing, together with other features, are illustrated in the accompanying drawings, in which- V Fig. 1 is a full sideelevation of a particular embodiment of the invention;

Fig. 2 is a partial front elevation of the machine;

Fig. 3 `is anenlarged side elevation, parts being broken away; Y

Fig. 1 is a horizontal section on the line 1f-4 of Fig. 2;

Figs. 5, 6 and 7 are fragmentary views in front elevation illustrating various positions of the work-engagement elements, and

Fig. 8 is a diagram showing the cycles through which the cam mechanism moves the parts. Y

Uponthe base frame 10 in vertical ways 12 is movably mounted a bracket 14 from the upper portion of which there extends horizontally a center`16, preferably conical, like the center of a lathe, and surrounded by a contact surface 17. This center is adapted to enter a .corresponding-.recess in a form 18, which has the shape of the lower portion of a leg from just below the knee to the ankle and which is of such circumference that the largest size of legging may be formed upon it. As illustrated, the center 16 is applied to the recess at the ankle end of the form though it can be oppositely placed if desired. In the other eX- tremity of the form is a like recess to receive a center 20, ,this center being Surrounded by a contact surface 21 and being carried, extending inV the direction of the y axis of the opposite center 16, upon the upper end of an arm 22 pivoted at 24 upon the bracket 14:. Rotatable in a bearing trunnion at 25 in the arm between its pivotal point and the center 20 is a screw 26 held against longitudinal movement by collars 28, 2S upon opposite sides of the arm. At the outer end of thescrew is a hand wheel 30 which may be turned by the operator to draw the screw in or out through a nut 32 pivoted upon the bracket. This allows the center. 2O to be separated from the center 16 a sufficient distance to enable tion it may be clamped by further rotation ofthe hand wheel, which presses thek contactin'g surfaces 17 and 21 firmly against the ends of the form..

v From the rear of the base rises an upright 34 on which a vertical rod 36 is mounted between short arms 88, 88 projecting forwardly. About the rod may swing a compound head or carrier having upper and lower sections 40 and 42, respectively, maintained in vertical alinement by a pin 44 rising from the lower section and entering an opening in the upper. The head may be moved about the rod 36 by the opera-tor to a position best shown in Fig. 1 of the drawings to yprepare the engaging elements it carries for co-operation with the work, or to either side of this [central position entirely clear of the form. In the firstmentioned location the head may be frictionally retained by a spring-pressed stud 45 mounted in the upri ht 84 and engaging the head section 40. onnected to each carrier section is a downwardly extending portion 46, these two portions` sliding over one another between the front face of the upright 34 and a cap plate 48 bolted thereto. At the lower extremities of the extensions are anti-friction rolls 50, the rolls of the sections 40 and 42resting respectively upon the tops of cams 52 and 54 fast upon a shaft 56 journaled in the base frame. The form of these cams is such that the head sections and members carried thereby will yperform a cycle of operations in fourfsuccessive periods, the character and purpose of which will later appear'. Fulcrumed upon opposite sides of the head section 40 on rods 58, 58 are two opposite series of angle levers 60, 60 situated in transversely aliiied pairs. Each of these levers 60 has three arms, one, 62, extending in a horizontal direction, 64 being an upwardly extending arm, while 66 projects downwardly. Hung upon the extremity of leach arm 62 and passing through openings in the lower head section it a work-engaging device 68, this, as illustrated, being of the well-known form disclosed in Patent No. 1,030,264, McFeely, granted June 18, 1912. Each of these work-engaging means includes a casing 70 at the lower end of which are workengaging jaws 72, 72, one of which is pivoted. At the upper end of the casing4 are oppositely projecting horizontal lugs 7 4, 7 4 so related to the lower head section 42 that they may be brought into contact with its `pairs of gripping jaws, toward one another upper surface by a movement of the head sections relatively to one another. VVi'thin the casing is mounted to 'move a slidekr 76 pivoted at 78 to the arm 62l of the lever. At the lower end ofthe rod a latch 80 is pivoted, projecting through an opening in the casing and having as one of its functions the maintenance of the gripping jaws in their closedy relation. The jaws may be released by pressure upon the rlatch applied outside the casing. The members 68' are arranged in opposite pairs upon corresponding pairs of levers 60, and between upward extensions 82 of the slides 76 of each pair is a helical spring 84 carried by thimbles 86, 86 sliding in a cylindrical opening in the head section 40. Theser springs exert their expansive force to move the lower ends of the engaging members, and therefore the to points above the form 18. Of each pair of levers 60, one has upon its arm 64 a nut 88 pivoted between bifurcations of the arm, while the arm 64 ofthe opposite lever'has a collar 90 similarly pivoted. Through the nut 88 is threaded a rod 92 with its inner end entering the opening in the collar 90. Surrounding each rod between the colla-r 90 and a collar 96 fast upon the rod is a helical spring 94. These springs, by their expansion, rock both levers of the pairs about their fulcruni points bringing the extremities of the arms 66 into contact with limiting surfaces 97 upon opposite sides of the head section 42. When tension is applied by the gripping members in their operation upon the work, the springs 94 are compressed when the pull becomes sufficiently great, and since either of the levers of a pair can independently compress their common spring the stress upon vthe work is equalized, the pull being the same on both sides. Outside 'the nut 88 each rod 92 has fast upon it a hand wheel 98, the hand wheels on adjacent rods being disposed uponv opposite sides of machine. The rotation of the rods by these hand wheels compresses the springs 94, and by this means the tension applied to the work before the springs yield may be varied to obtain the proper-stretching effect at different points along the edges of the sheet of material. yJournaled inthe head section 42, extending longitudinally thereof, is a shaft 100v having fixed at'opposite extremities arm 102, 102, these arms carrying at their lower ends a bar 104. This bar is in horizontal alinement with the latches 80 of all the gripping members. Upon the outer end of the yshafty 100, convenient for manipulation by the operator, isa handle 106 through which the bar 104 may be swung in either direction to simultaneously contact with all the latches of a series of the gripping members to trip them and release the jaws. The handle and bar are 130 vet tively, of the fulcrum rods 58, 58.

normally maintained in afcentral posit-ion with the latter element out of engagement with the latches by a spring-pressed stud 108 which may occupy a recess in a vertical surface of the head section 42.

The extent of inward movement of the gripping members toward one another horizontally above the `edges ofthe sheet S of material secured to the form is determined byrods 110, 110, one for each-series, these rods running horizontally longitudinally of the head section near the inner faces of the lower extremities of the gripping members. The rods 110 are carried by pairs of arms or controlling members 112, 112 and 114, 114 hung upon the outer and inner ends, respec- These arms have at their` lower ends contact portions 116 variably controlling the position of the rods by engagement with cam surfaces 118, 120 on the arm 22 and bracket 14, respectively, adjacent to the centers 20 and 16. The cam surfaces with which the arms 112 and 114 contact correspond in contour and dimensions with the adjacent portions of the form, and the extent to which 4the arms move over the surfaces in the descent of the gripping member carrier will depend on the ini tial vertical relation of the form and gripping members.4 As here disclosed, the position of the form is altered in accordance with the size of the legging' to be formed. Assuming there are to be ve sizes, asv -14, 14%, 15, 15g and 16, the lowerportion of the bracket 14 rests upona cam 122 fixed upon a transverse shaft 124 journaled in the base vframe. Upon one extremity of the shaft 124 is a hand wheel 126 through which the operator may rotate it and an index wheel 128 bearing upon its periphery the size numbers previously mentioned. lith this index wheel co-operates an index finger 130 secured to the frame. The cam is formed in five successive steps of increasing diameter, the radial distance of these steps from the axis ot' the shaft being such that when a particular cam surface is lnought into .contact with the bracket by the rotation of the hand wheel the form will be raised or lowered to a position at which the upper edges of the sheet Vof material fixed to the form will be in theproper relation to the material-engaging members. Generally the purpose of this adjustment is to keep the upper edges of the sheet in the samehorizontal plane. To retain the form-supporting elements against upward movement upon the ways 12 under the tension` applied to the material upon the form, the cam 122 has rotating` with it a cam 132 having a contour similar to the cam 122 but with the steps oppositely placed. lith the periphery of this cam 132 contacts the angular end of a member 134 pivoted at 136 on the lower portion of the bracket 14. As the cam 122 is turned to face` always in contact with the port-ion 134 so that in all positions `of the form a posi*- tive` stop against upward movement is provided. The rods 110 shifted by the contact of the arms112 and 114'with the cam surfaces118 and 120 will position the jaws of the grippers in lines not onlyV corresponding tothe upper edges of the sheet of material of Y the particular size being operatedom'but also in accordance with the general inclination of the edges of the sheet as it is applied to the form. Thisv s because the different diameters of the cam surfaces 118, 120 will produce a convergence of the rods 110'to ward the rear in accordance withthe decreaseV in diameter -of the form. Consequentlywhen the material is brought into proximity with the jaws by the movement of the headit may.`readily be introduced between them by the operator. The arms 112, 114 are held tothe positionsto which they are expandedby the cam surfaces by means oflatch bars 135 and 136 pivoted respectively upon one of the arms of each pair. These latches are toothed at their free ends and are drawn by springs 138 extending between them and the arms into engagement with detente 140 lixed to the opposite arm of each pair from that upon which the latch bar is pivoted. To release the controlli-ng armsV at the completion of an operation by a relative movement between the head sections under the influence of the cams 52 `and 54, the latch bar 135 has a screw 142 threaded through it so that when the head section 42 recedes from the section 40 the upper end of the yscrew comes intoV contact with the hub of the handle 106. By this the latch bar is pressed down untilits teeth are separated from the detent` 140,' whereupon the gripraise the form the cam 132 maintains a. surpingmembers 68 assume their normal ini ward positionsunder the influence of the springs 84. The inner latch bar 136 is released by its contact with `a screw 144 threaded through the head section .ln the base 10 at each side of the form in ways 146 is mounted a sliding block or support 148 for a series of clamping members 150. These clamping members consist of slides lying in channels formed in the upper faces 4of the supports, which channels are closed by cap plates 152.3At` theinner or work-engaging extremities-of the slides are removable plates 154 for contact with the material upon theform, these preferably being `of solne such metal as brass whichdoes not discolor leather by its contact and having their ends shaped to conform vto the leg form. The work-engaging edges of the members 150`occupy a practically continuous line to enable them to clamp the material against the form at every point in a horizontal direction. The clamping member supports 148may be moved manually by the* the section extensions 46 ride over the cam surfaces a and l), a result of the rotation of the cams 52 and followingthe first depression of the treadle 210 by the operator, the head section 40 first moves down while the section 42 remains stationary, the contact of the lues 74 uoon the casinofs of the n l an gripping members with the upper surface of the head 42* causing the `Jaws-to separate.

Thereafter, during the later portion ofthe first period, the head sections move together, until at the end of the first period lthey are in proximity to the form. During this -time the cam 194 moves its surfaces c and Pi over the rolls of the lever 186, rotating the cam shafts 1'70 to free the springs 167. This is preliminary to a later operation of the shaft. At the points indicated by the numeral 2 the cams are .all automatically stopped with the parts they actuate appearing as in Figs.A

l to 4. `A second depression of the treadle 210 by the operator resultsin the surfaces CZ and e 0f the cams 52 and 54, respectively,

moving the head section v40 upward while section 42 remains fixed until lthe vlugs 74 are separated from the head surface so `thatl the jaws may be closed upon the edges of the material on the form; This is followed by an upward movement of the head sections together to tension the materialen thejform. Thecain 194 during this period, by its Asurfaces f and g, causes adwell of the elements which it actuates. The relation of theelements is shown by Fig. 6. Upon thethird depression of the treadle 210 the cams rotate from the point 8. 'During this time thel surfaces 7L and j of the cams 52 and 54 are such that the gripping members remain inac- The surfaces e' and c of the cam 194 rotive. tate the shafts 170 so that the clamping members are forced into engagement with the material and the latter against the form.

(F ig. 7). The fourth treadle depression leads to a retention of the clamping members in their work-engaging positions under `the influence of the surfaces g and f on the cam- 194 while the head sections 40 and 42 Vare raised to their normal Vposition Aby the surfaces /t and Z of the cams 52 and 54.

Considering the general operation of the machine, the form 18 having been'placed between its centers with the head 40`42 turned to one side, the operator, by means ofthe hand wheel 126 and index members 128 and 130, positions the form for the particular size of legging to be operated upon. Then r with the curved side of the form upper'- most, he bends a sheet of leather over said form and at its opposite edges tacks the sheet to the extremities of the vform Vas indicated atT in Fig. 6 of the drawings.v Thereupon, he rotates the form until the tacked side is underneath and locks the form in thisv position through the pressure of the contact surfaces 17 and 21. Moving the gripping head toits central position and holding the freev edges ofthe sheet vertically, 'the operatordepresses the treadle 210 for the first time.V vThe elements, as far as mechanical actuation is concerned, then assume the positions illustrated-in Figs. 1 to. 4 of the drawingsl and as just described in connection with the statement of thecam-controlled cycle-1 `The'gripping jaws now being openV and adjacentto the edges `of lthe work the operator inserts the sheet between them and again forces down the treadle. This causes theja-wstojclose and draw u the material into its stretched position Figi 6). kFol-` lowing this, the `operator simultaneously slides vin the opposite blocks 148, as shown in Figs. 2 and4, whichare locked by'the engagement of the members 156 and 158. This 1s preparatory to a third depression of the treadle 210, which causes the rotation of the shafts 170 to yieldingly pressin the clamping members 150. By this movement the gripping members are Vdrawn over the form as the-edges ofthe ,material move 1n advance of the clamping members. I The sheet now being held against :the form by these members150,the gripping .jaws are released by the operator oscillating the bar 104 against theopposite latches 80, and the fourth', treadle depression causes the gripping members to belifted totheir Vuppermost position from which they'may be swung to oneside clear of theV work. The operator now tacks the clampedA edges at appropriate.
